The upgrade to NetBSD 1.1 is a binary upgrade; it would be prohibitive
|
|
|
|
to make users upgrade by compiling and installing the 1.1 sources, and
|
1994-09-17 23:02:58 +04:00
|
|
|
it would be very difficult to even compile a set of instructions that
|
1995-11-29 02:56:58 +03:00
|
|
|
allowed them to do so. Because of the many changes to the system, it
|
|
|
|
is difficult impractical to upgrade by recompiling from the sources
|
|
|
|
and installing.
|
1994-09-17 23:02:58 +04:00
|
|
|
|
|
|
|
To do the upgrade, you must have the appropriate kernel-copy floppy
|
1995-11-29 02:56:58 +03:00
|
|
|
image on a disk, and the upgr11.fs floppy image on another. You must
|
|
|
|
also have at least the "base11" binary distribution set available,
|
1994-09-17 23:02:58 +04:00
|
|
|
so that you can upgrade with it, using one of the upgrade methods
|
|
|
|
described above. Finally, you must have sufficient disk space
|
|
|
|
available to install the new binaries. Since the old binaries are
|
|
|
|
being overwritten in place, you only need space for the new binaries,
|
|
|
|
which weren't previously on the system. If you have a few megabytes
|
|
|
|
free on each of your root and /usr partitions, you should have enough
|
|
|
|
space.
|
|
|
|
|
|
|
|
Since upgrading involves replacing the boot blocks on your NetBSD
|
|
|
|
partition, the kernel, and most of the system binaries, it has the
|
|
|
|
potential to cause data loss. You are strongly advised to BACK UP ANY
|
|
|
|
IMPORTANT DATA ON YOUR DISK, whether on the NetBSD partition or on
|
|
|
|
another operating system's partition, before beginning the upgrade
|
|
|
|
process.
|
|
|
|
|
|
|
|
To upgrade your system, follow the following instructions:
|
|
|
|
|
|
|
|
Boot your machine using of the appropriate kernel-copy floppy.
|
|
|
|
When presented with the boot prompt (the prompt begins with
|
|
|
|
"Boot" and ends with ":-"), hit return.
|
|
|
|
|
|
|
|
You will be prompted to insert a file system floppy. Remove
|
1995-11-29 02:56:58 +03:00
|
|
|
the kernel-copy floppy and insert the upgr11 floppy, then hit
|
1994-09-17 23:02:58 +04:00
|
|
|
any key to continue booting.
|
|
|
|
|
|
|
|
While booting, you will probably see several warnings. You
|
|
|
|
should be warned that no swap space is present, and that
|
|
|
|
init(8) cannot find /etc/rc. Do not be alarmed, these are
|
|
|
|
completely normal. When you reach the prompt asking you for a
|
|
|
|
shell name, just hit return.
|
|
|
|
|
|
|
|
You will be presented with some information about the upgrade
|
|
|
|
process and a warning message, and will be asked if you wish
|
|
|
|
to proceed with the upgrade process. If you answer
|
|
|
|
negatively, the upgrade process will stop, and your disk will
|
|
|
|
not be modified. If you answer affirmatively, the upgrade
|
|
|
|
process will begin, and your disk will be modified. You may
|
|
|
|
hit Control-C to stop the upgrade process at any time.
|
|
|
|
However, if you hit it at an inopportune moment, your system
|
|
|
|
may be left in an inconsistent (and possibly unusable) state.
|
|
|
|
|
|
|
|
You will be asked if you wish to upgrade your file systems to
|
|
|
|
the new file system format. If you do, reply affirmatively.
|
|
|
|
If you don't have your file systems upgraded now, you should
|
|
|
|
probably do it manually after the install process is complete,
|
|
|
|
by using "fsck -c 2". Read the fsck(8) manual page for more
|
1995-11-29 02:56:58 +03:00
|
|
|
details. Note that this step is only important when upgrading
|
|
|
|
from a pre-NetBSD 1.0 release.
|
1994-09-17 23:02:58 +04:00
|
|
|
|
|
|
|
The upgrade program will then check your root file system,
|
|
|
|
and, if you approved, will upgrade it to the new file system
|
|
|
|
format. It will then mount your root file system on /mnt.
|
|
|
|
|
|
|
|
If your file systems are being upgraded, the upgrade script
|
|
|
|
will copy the new fsck(8) program to your hard disk and
|
|
|
|
upgrade your remaining file systems.
|
|
|
|
|
|
|
|
The upgrade program will then automatically replace the boot
|
|
|
|
blocks on your disk with newer versions, and mount all of your
|
|
|
|
file systems under /mnt. (In other words, your root partition
|
|
|
|
will be mounted on /mnt, your /usr partition on /mnt/usr, etc.)
|
|
|
|
|
|
|
|
If you don't already have the NetBSD distribution sets on your
|
|
|
|
disk, look in the installation section for information on how
|
1994-10-18 10:17:04 +03:00
|
|
|
to transfer them to your disk.
|
|
|
|
|
|
|
|
If you have only one floppy drive, and don't have the disk
|
1994-10-18 10:38:46 +03:00
|
|
|
space to copy all of the distribution onto the hard drive, you
|
|
|
|
can do the following:
|
|
|
|
|
1994-10-18 10:17:04 +03:00
|
|
|
Install a kernel on the hard drive as detailed a few
|
1994-10-18 10:38:46 +03:00
|
|
|
paragraphs below, then boot off the hard drive. Now
|
|
|
|
you can copy and install distribution sets
|
|
|
|
incrementally from your lone floppy drive.
|
|
|
|
|
1994-10-18 10:17:04 +03:00
|
|
|
Once the distribution sets are transferred to your disk,
|
|
|
|
continue here. (Obviously, if the NetBSD distribution sets
|
1994-10-18 10:38:46 +03:00
|
|
|
are already on your disk, because you've transferred them
|
|
|
|
before starting the upgrade process, you don't need to
|
|
|
|
transfer them again now!)
|
1994-09-17 23:02:58 +04:00
|
|
|
|
|
|
|
After the software has been transferred to the machine (or
|
|
|
|
mounted, in the case of upgrading via NFS), change into the
|
1995-11-29 02:56:58 +03:00
|
|
|
directory containing the "base11" distribution set. Once you
|
1994-10-18 10:38:46 +03:00
|
|
|
are there, run the "Set_tmp_dir" command, and hit return at
|
|
|
|
the prompt to select the default answer for the temporary
|
1994-09-17 23:02:58 +04:00
|
|
|
directory's path name. (It should be the path name of the
|
|
|
|
directory that you're in.)
|
|
|
|
|
1995-11-29 02:56:58 +03:00
|
|
|
Run the command "Extract base11" to upgrade the base
|
1994-09-17 23:02:58 +04:00
|
|
|
distribution.
|
|
|
|
|
|
|
|
Repeat the above two steps for all of the sets you wish to
|
|
|
|
upgrade. (For each, change into the directory containing the
|
|
|
|
set, run "Set_tmp_dir" and accept the default path name, then
|
|
|
|
run the "Extract <setname>" command.)
|
|
|
|
|
|
|
|
If you were previously using the security distribution set,
|
|
|
|
you MUST upgrade to the new version, or you will not be able
|
|
|
|
to log in when the upgrade process is complete. Similarly, if
|
|
|
|
you were not previously using the security set, you must NOT
|
|
|
|
upgrade to the new version.
|
|
|
|
|
|
|
|
When you are done upgrading all of the distribution sets you
|
|
|
|
wish to upgrade, issue the command "Cleanup". It will clean
|
|
|
|
up the installation, by remaking some system databases. When
|
|
|
|
it is complete, you should use "halt" to halt the system.
|
|
|
|
|
1995-11-29 02:56:58 +03:00
|
|
|
When the system is halted, remove the "upgr11" floppy from
|
|
|
|
the floppy drive, and replace it with the NetBSD 1.1
|
1994-09-17 23:02:58 +04:00
|
|
|
kernel-copy floppy that you previously booted from. Reboot
|
|
|
|
with that floppy.
|
|
|
|
|
|
|
|
Once again, you will be prompted to insert a file system
|
|
|
|
floppy. DO NOT replace the kernel-copy floppy, just hit any
|
|
|
|
key.
|
|
|
|
|
|
|
|
Again, While booting, you may see several warnings. You may
|
|
|
|
be warned that no swap space is present, that init(8) cannot
|
|
|
|
find /etc/rc, and that one or more databases with names like
|
|
|
|
"pwd.db" cannot be found. Do not be alarmed, as, again, these
|
|
|
|
are completely normal. Hit return at the prompt asking you
|
|
|
|
for a shell name.
|
|
|
|
|
|
|
|
You will be presented with a shell prompt, at which you should
|
|
|
|
enter the "copy_kernel" command. It will ask you what
|
|
|
|
partition to copy the kernel to, and you should reply with the
|
|
|
|
name of your root partition (e.g. sd0a or wd0a).
|
|
|
|
|
|
|
|
You will be asked if you are sure that you want to copy the
|
|
|
|
kernel. Reply affirmatively, and it will check the file
|
|
|
|
system on your root partition, mount it, and copy the kernel.
|
|
|
|
Once the kernel is copied, you should use "halt" to halt the
|
|
|
|
system.
|
|
|
|
|
|
|
|
Once the system is halted, remove the kernel-copy floppy from
|
|
|
|
the floppy disk drive, and hit any key to reboot.
|
|
|
|
|
1995-11-29 02:56:58 +03:00
|
|
|
Your system has now been upgraded to NetBSD 1.1.
|
1994-09-17 23:02:58 +04:00
|
|
|
|
1995-11-29 02:56:58 +03:00
|
|
|
After a new kernel has been copied to your hard disk, your
|
|
|
|
machine is a complete NetBSD 1.1 system. However, that
|
1994-09-17 23:02:58 +04:00
|
|
|
doesn't mean that you're finished with the upgrade process.
|
|
|
|
There are several things that you should do, or might have to
|
|
|
|
do, to insure that the system works properly.
|
|
|
|
|
|
|
|
First, if you did not upgrade your file systems to the new
|
1995-11-29 02:56:58 +03:00
|
|
|
file system format during the upgrade process, and you are
|
|
|
|
upgrading from a pre-1.0 NetBSD, you may want to do so now,
|
|
|
|
with "fsck -c 2". If you are unsure about the process, it's
|
|
|
|
suggested that you read the fsck(8) manual page.
|
1994-09-17 23:02:58 +04:00
|
|
|
|
1995-11-29 02:56:58 +03:00
|
|
|
Second, you will probably want to get the etc11 distribution,
|
1994-09-17 23:02:58 +04:00
|
|
|
extract it, and compare its contents with those in your /etc/
|
|
|
|
directory. You will probably want to replace some of your
|
|
|
|
system configuration files, or incorporate some of the changes
|
|
|
|
in the new versions into yours.
|
|
|
|
|
|
|
|
Third, you will probably want to update the set of device
|
|
|
|
nodes you have in /dev. If you've changed the contents of
|
|
|
|
/dev by hand, you will need to be careful about this, but if
|
|
|
|
not, you can just cd into /dev, and run the command "sh
|
|
|
|
MAKEDEV all".
|
|
|
|
|
|
|
|
Fourth, you must deal with certain changes in the formats of
|
|
|
|
some of the configuration files. The most notable change is
|
|
|
|
that the "options" given to many of the file systems in
|
|
|
|
/etc/fstab or by hand have changed, and some of the file
|
1995-11-29 02:56:58 +03:00
|
|
|
systems have changed names. *IMPORTANT*: ANY INSTANCES OF "ufs"
|
|
|
|
IN /etc/fstab MUST BE CHANGED TO "ffs". To find out what the
|
|
|
|
new options are, it's suggested that you read the manual page
|
|
|
|
for the file systems' mount commands, for example mount_nfs(8)
|
|
|
|
for NFS. (Note that the information for mounts of type "ffs",
|
1994-09-17 23:02:58 +04:00
|
|
|
i.e. Fast File Systems, are contained in the mount(8) man
|
|
|
|
page.)
|
|
|
|
|
|
|
|
Finally, you will want to delete old binaries that were part
|
|
|
|
of the version of NetBSD that you upgraded from and have since
|
1995-11-29 02:56:58 +03:00
|
|
|
been removed from the NetBSD distribution. If you are
|
|
|
|
upgrading from a pre-1.0 NetBSD, you might also
|
1994-09-17 23:02:58 +04:00
|
|
|
want to recompile any locally-built binaries, to take
|
|
|
|
advantage of the shared libraries. (Note that any new
|
|
|
|
binaries that you build will be dynamically linked, and
|
|
|
|
therefore take advantage of the shared libraries, by default.
|
|
|
|
For information on how to make statically linked binaries,
|
|
|
|
see the cc(1) and ld(1) manual pages.)
|
